Category: E - Publication & Communication (Analysis Methods)
VS Level: Full (5-Phase)
Tier: Flagship
Icon: 📈📊
Overview
Comprehensive guide for both quantitative and qualitative analysis methods appropriate for research design and data characteristics.
Applies VS-Research methodology to avoid monotonous analyses like "recommend t-test" or "just do thematic analysis,"
presenting methodological diversity optimized for research questions across paradigms.
VS-Research 5-Phase Process
Phase 0: Context Collection (MANDATORY)
Must collect before VS application:
Required Context:
- research_question: "Relationship/difference to analyze"
- independent_variable: "Type (continuous/categorical), number of levels"
- dependent_variable: "Type (continuous/categorical), number of levels"
- design: "Independent/Repeated/Mixed"
Optional Context:
- control_variables: "Covariate list"
- sample_size: "Current or expected N"
- target_journal: "Target journal level"
Phase 1: Modal Analysis Method Identification
Purpose: Explicitly identify the most predictable "obvious" analysis methods
## Phase 1: Modal Analysis Method Identification
⚠️ **Modal Warning**: The following are the most commonly used analyses for this design:

|--------------|---------|------------|------------|
| [Method1] | 0.92 | 60%+ | [Limitation] |
| [Method2] | 0.88 | 25%+ | [Limitation] |
➡️ Confirming if this is optimal and exploring more suitable alternatives.
Phase 2: Long-Tail Analysis Method Sampling
Purpose: Present alternatives at 3 levels based on T-Score

- Suitable for: Methodology-oriented journals
**Direction C** (T < 0.3): Innovative approaches
- [Method]: [Description]
- Advantages: Latest methodology, high differentiation
- Suitable for: Top-tier journals
Phase 3: Low-Typicality Selection
Purpose: Select method most appropriate for research question and data
Selection Criteria:
- Statistical Fit: Assumption satisfaction, data characteristics
- Research Question Alignment: Optimal for hypothesis testing
- Methodological Contribution: Differentiation potential
- Feasibility: Software, expertise
Phase 4: Execution
Purpose: Provide specific guidance for selected analysis method
## Phase 4: Analysis Execution Guide
### Primary Analysis Method
[Specific guidance]
### Assumption Checks
[Procedures and code]
### Effect Size
[Calculation and interpretation]
Phase 5: Suitability Verification
Purpose: Confirm final selection is optimal for research
## Phase 5: Suitability Verification
✅ Modal Avoidance Check:
- [ ] "Was basic t-test/ANOVA sufficient?" → Review complete
- [ ] "Are there more suitable modern alternatives?" → Review complete
- [ ] "Is methodological contribution possible?" → Confirmed
✅ Quality Check:
- [ ] Statistical assumptions satisfied? → YES
- [ ] Accurately answers research question? → YES
